Problems solved by technology

However, more and more excellent media formats are emerging, such as H265, SVAC, AV1, etc., so the media attributes cannot be transmitted purely at the signaling level, and the above conversion methods are invalid.
[0006] In view of this problem, there are some simple solutions, such as manually marking the media format of each connected video source in the system, or trying to use one encoding format in a system, but these methods have not completely solved it. problems, making the overall media system lack of interaction

Abstract

The present invention provides a protocol conversion method and device in the media stream forwarding process. The method includes: receiving a data request initiated by an RTSP client, and establishing a session mapping; extracting key content in the data request, and serving the SIP according to the key content The terminal initiates a SIP session stream; receives the media stream sent by the SIP server, and analyzes the media stream, frames and unpacks it, and then stores it in the buffer queue, wherein the parsed content includes the media format of the media stream; Packet sent to RTSP client. This method can convert the GB28181 protocol into the RTSP protocol, and can support different types of media formats, thereby effectively realizing the resource access of the RTSP client to any media encoding format of the GB28181 protocol, facilitating the continuous development and evolution of the media encoding format, and greatly improving It improves the versatility and adaptability of media interaction.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a protocol conversion method in the media stream forwarding process, a protocol conversion device in the media stream forwarding process, a non-transitory computer-readable storage medium and a computer device. Background technique [0002] The video surveillance system involves the interconnection between many devices and platforms. In the process of interconnection, it involves the conversion of various protocols. Among them, the GB28181 protocol is converted into RTSP (Real Time Streaming Protocol, real-time streaming protocol) This method of agreement is the most common. Due to the differences in the specifications of the two protocols, the current video security system has the following defects at the protocol conversion level: [0003] RTSP is based on the server / client architecture. RTSP 2.0 version defines the method of RTSP media playback, which is used to...
